Base app for Read/Write apps in Go

TODO add lots more info!

Steps to create a new read/write app

• Copy an existing app
• Rename the puppet folder to a new class name, e.g. ft-org_rw_nweo4j
• Go edit all the files in the manifests folder to match that change, using e.g. org_rw_neo4j
• Similarly with the Modulefile
• Add the exe file into .gitignore
• Amend main.go to specify the details of the command line args
• Implement Service for your service
• Add a model for your service
• Add a healthcheck for your service
• Done!
